I've had Vista installed on my Macbook Pro under Bootcamp for a while now. It's an OEM edition, bought off eBay. It's the real deal, with all the holograms, stickers and everything. It was all working like a treat, until... Last week Apple sent down a firmware upgrade for my MacBook pro. The next time I booted under Vista, I was told the my Hardware Configuration has changed and that I needed to re-activate. I tried that, but then it said that my copy of Vista was already activated and that I should buy a new copy. Like an idiot I called Microsoft support only to be told that the problem was that I had an OEM copy and that I should buy a new retail copy, or they would not support me. I'm sure they couldn't help me anyway, the guy was clearly working off a script and had no idea what I was talking about. Any suggestions?
